dark hazel, their shafts narrowly buff, their outer webs buffy brown 

 faintly vermiculated with dusky, and, on the scapulars, with pale gray 

 and externally suffused with dark hazel; secondaries dark olive-brown 

 to sepia, externally and terminally blotched and freckled with light 

 ochraceous-buff, the terminal freckling on the inner web tinged with hazel ; 

 upper wing coverts similar but many of them with blackish-brown blotches 

 on their inner webs and the pale freckling extending on the inner webs 

 to a greater degree ; primaries dark dull sepia to clove brown, externally 

 freckled with light ochraceous-buff, but only sparingly ; back, lower back, 

 rump, and upper tail coverts reveal two fairly distinct color phases^ — one 

 has these parts dusky isabelline to buffy brown with dark shafts and more 

 or less freckled transversely with dusky, especially on the more posterior 

 parts; the other with the back and lower back vinaceous-fawn to fawn 

 color obscurely crossed by widely spaced narrow dusky slate bars; the 

 rump and upper tail coverts dark sayal brown to snuff brown with dusky 

 shafts and tranverse freckling; rectrices Brussels brown flecked, and 

 basally blotched, with dark, dull sepia; chin and upper throat whitish; 

 lower throat and breast between neutral gray and dark gull gray ; upper 

 abdomen, sides, and flanks, ochraceous-buff to cinnamon-buff, darkening 

 laterally to clay color ; thighs ochraceous-buff barred with fuscous ; under 

 tail coverts similar ; middle of lower abdomen whitish ; under wing coverts 

 dull sepia to pale clove brown ; iris reddish brown ; bill black, becoming 

 brownish horn color at the tip; tarsi and toes plumbeous. 



Adult female. — Forehead, crown, and occiput dark Front's brown to 

 chestnut-brown; upperparts of body, wings, and tail as in adult male; 

 the two color phases present — vinaceous-fawn and buffy brown on the 

 backs, as in the males ; no orange-rufous on the sides of head as in the 

 males, this color being replaced by dark olive-brown, the feathers of 

 the cheeks and sides of neck with white shafts ; a row of dusky-tipped 

 white feathers from lores to, under, and behind the eye expending to the 

 fMDsteroIateral angle of the occiput; immediately below this a dark choco- 

 late band behind the eye ; chin and upper throat white ; lower throat and 

 breast antique brown to amber brown, many of the feathers decidedly 

 grayish broadly edged with antique brown; upper and lateral parts of 

 abdomen white, barred with sepia to dusky sepia ; thighs similar but less 

 strongly or distinctly barred ; most of middle lower abdomen white ; under 

 tail coverts ochraceous-buff barred with fuscous, under wing coverts 

 dull sepia. 



Juvenal male.^* — Similar to adult female but darker, less rufescent 

 above and on the lower throat, breast, and abdomen ; forehead, crow'n, 

 occiput, nape, and interscapulars between clove brown and dark mummy 

 brown, the feathers with minute pale smoke-gray spots along the distal 



°* The only example seen was a male, but probably the sexes are alike in this 

 plumage.
